MCP (Model Context Protocol)

Agents access external tools via MCP. The AgentCore Gateway hosts MCP servers, and each agent calls tools through SigV4-authenticated HTTP connections.

All MCP tool calls automatically inject user_id and project_id, ensuring data isolation between users.

Session Management

IDP Agent and Voice Agent persist conversation history to S3.

s3://session-storage-bucket/
└── sessions/
    └── {user_id}/
        └── {project_id}/
            └── {session_id}/
